This calibration procedure will automatically calibrate the initial and the maximum current for the left and the right pump forward solenoids. This calibration will also calibrate the currents for the left and the right motor solenoids. During the calibration procedure, the machine will move.Note: In order to place the machine on stands, refer to Testing and Adjusting, "Service Brake Pedal - Test".

Use the ET to calibrate the following solenoids:
Left pump forward solenoid
Right pump forward solenoid
Left motor solenoid
Right motor solenoidCalibration is required in the following situations:
A pump or a motor is replaced or a pump or a motor is serviced.
The hystat ECM is replaced or the hystat ECM is removed for service.Use the ET in order to calibrate the solenoids. Select Service from the main menu. Then, select "CALIBRATION" from the drop-down menu. Select the "Forward Pump and Motor Solenoid Calibration" from the selection menu. Follow the instructions that are provided.The hystat ECM must detect the following conditions before starting the calibration procedure:
The joystick must be in the neutral position.
The engine must be running and the engine is set to high idle.
There are No Active Diagnostics.
The parking brake switch must be released.If any of these conditions are not met during the calibration, the procedure is aborted immediately.Note: The hydraulic oil temperature must be between 40 °C (104 °F) to 55 °C (131 °F).
